4 Stephen Jay Gould Quotes on Logic

Stephen Jay Gould quotes on logic

53. I despair of persuading people to drop the familiar and comforting tactic of dichotomy. Perhaps, instead, we might expand the framework of debates by seeking other dichotomies more appropriate than, or simply different from, the conventional divisions. All dichotomies are simplifications, but the rendition of a conflict along differing axes of several orthogonal dichotomies might provide an amplitude of proper intellectual space without forcing us to forgo our most comforting tool of thought.

70. I strongly reject any conceptual scheme that places our options on a line, and holds that the only alternative to a pair of extreme positions lies somewhere between them. More fruitful perspectives often require that we step off the line to a site outside the dichotomy.

139. [T]ruly grand and powerful theories [:] do not and cannot rest upon single observations. Evolution is an inference from thousands of independent sources, the only conceptual structure that can make unified sense of all this disparate information. The failure of a particular claim usually records a local error, not the bankruptcy of a central theory. [:] If I mistakenly identify your father's brother as your own dad, you don't become genealogically rootless and created de novo. You still have a father; we just haven't located him properly.

193. He confronts a basic tool of the measurers-the statistical technique called factor analysis, developed by the influential English psychologist Charles Spearman-and demonstrates persuasively how factor analysis led to the cardinal error in reasoning of confusing correlation with cause, or, to put it another way, of attributing false concreteness to the abstract. It is this sort of performance that makes the book's eventual refutation of Arthur Jensen seem incidental, for it is far more absorbing to have our powers of reason challenged than it is to have our social consciences shaken.
